Selecting suitable ear adapters for
optimum fit of the earbuds
XS
The perceived sound quality including bass performance and the
best possible noise cancellation of the earphones depends to a large
extent on the correct fit of the earbuds in the ear.
▷
Pull the ear adapter away from the in-ear sound tunnel.
▷
Mount the new ear adapter to the in-ear sound tunnel. Ensure that
it locks into place.
▷
Test which ear adapter size gives you the best sound quality and
the best wearing comfort.
You can choose between 4 different ear adapters in size XS, S, M
and L. The ear adapters must fit snugly in the ear canal and com-
pletely seal your ears.

▷
Assign the right earphone to your right ear and the left earphone
to your left ear.
▷
Insert the earbuds at a slight angle into the ears and twist them
slightly into the ear canal so that they sit comfortably and snugly
in the ear canal (> 20).
You can use the right earbud alone without using the left ear-
bud. The left earbud, however, cannot be used alone.
